UnverifiedAI weather models have achieved approximately a 10,000-fold improvement in computational efficiency compared to traditional NWP.74% similarUnverifiedOnce an AI weather model has been trained, generating a forecast takes only seconds to minutes, far less than the hours of computation required by traditional NWP.73% similarUnverifiedGraphCast can complete a 10-day global forecast in under one minute on a single TPU, its accuracy surpasses traditional numerical models on multiple metrics, and the results were published in Science.64% similarUnverifiedGraphCast is based on graph neural networks, while Pangu-Weather and FengWu are based on Transformers; they generally adopt autoregressive forecasting with a 6-hour time step, with forecast lead times typically within 10 days.62% similarUnverifiedIn agentic scenarios, large models can be used to generate high-quality task execution trajectories, which are then used to fine-tune models that are 10–100 times smaller in parameter count to perform specific subtasks.61% similar
